CATCH-BASIN COVER.

SPECIFICATION forming part of Letters Patent No. 784,271, dated March 7, 1905.

Application filed March 21, 1904. Serial No. 199,287.

To (all 1072/0772 it may concern:

Be it known that 1, HIRAM W. MO DONALD, a citizen of the United States, residing at Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Catch-Basin Covers, of which the following is a specification.

Ever since the introduction of iron sewerinlets or catch-basin covers it has been a desideratum to' secure surface-covers of this type which might be readily adjusted so as to conform to any desired depth of gutter.

(arenerally my invention relates to a basincover of the type above mentioned and commonly employed for storm-water basins, in which the inlet admitting thesewage-water is regulated by an adjustable face-plate.

The invention particularly aims to obviate the necessity for using bolts or fastenings of any kind for positioning the face-plate upon the cover, and with the foregoing in view 1 utilize a face-plate movably mounted and which is fixed at the necessary adjustment by a permanent foundation.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

' While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a perspective View, partially in section, showing the application of the inven tion to the ordinary small catch-basin atpresent in general use. Fig. 2. is a vertical sectional view, parts being broken away, bringing out more clearly all relative disposal of the face-plate upon the basin-cover when the latter is in working position. Fig. 3 is adetail perspective view of the face-plate alone, showing more clearly the grate carried thereby. Fig. 4 is a plan view of the base-plate of the cover. Fig. 5 is a detail view bringing out more clearly the sectional construction of the grate-bar's.

Fig. 6 is a sectional view of the cover, illustrating the assemblance and manner of securing the parts preparatory to shipment or transportation.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The basin-cover constructed in accordance with my invention in general form may be of any of the various types now in use. The cover comprises, essentially, a body 1, a top plate 2, the base-plate 3, and the manhole lid or cover i. As shown in the drawings, (see Fig. 1,) the base-plate 3 rests directly upon a small catch-basin 9, in which the outlet-pipe 5 is walled. The size of the basin is immaterial within the contemplation of my invention, and an elbow or any other style of trap may be connected with the outlet-pipe aforesaid. The construction of basin as above mentioned is nowgenerally used for storm-water sewers, and the front wall 6 of the basin is designed to furnish a foundation for fixing the adjustment of my face-plate (indicated by the numeral 7) at any required elevation, dependent upon the depth of the gutter required. \Vhen required for direct connection with the sewerpipe, the outlet 8 of the base-plate 3, which leads into the basin 9, is reduced to connect with pipe of any preferred size.

The face-plate 7 is mounted upon the front 10 of the cover and, as shown, partially closes the inlet-opening 11 therein. The invention resides in the particular mounting of the faceplate 7 and manner of positioning same whereby said plate may be lowered or elevated relative to its position upon the cover, so that the latter may be used readily for gutters of var-- ried depths. Projected rearwardly from the upper edge portion of the face-plate '7 is a guide-flange 12, and extended upwardly from the guide-flange 12 are guide-standards 13.

The guide-standards 13 are located at the edge portions of the flange 12 and are received between the sides of the body 1 of the cover. The standards 13 move in vertical guides formed by providing ribs lat, cast integrally with the sides of the cover aforesaid, at points adjacent the inlet-opening 11.

The guideflange 12 relative to its length is somewhat longer than the face-plate 7, the end portions of said flange extending in rear of the front of the cover, as will be readily noted by reference to Fig. 1, the face-plate 7, however, resting flush With the outer face of the front 10. The standards 13 are not only utilized as guide members, but comprise supporting means for the grate, which latter is designed to prevent entrance of large sticks or other foreign matter into the basin 9. The grate consists of a supporting-bar 15, connecting the standards 13, which bar is preferably of squared form in cross-section. The grate members 16 comprise sections 16 and 16 The section 16 is provided with lugs 17, adapted to be received by openings 18 in the section 16". The sections 16 and 16 are adapted to embrace the supporting-bar upon opposite sides, each being provided With a seat 19 to receir e a body of said bar. The sections of the'grate-bars are secured together by riveting the lugs 17 of the section 16*after same have been passed through the openings in the section 16". The grate-bars being removably attached may be provided in any suitable number dependent upon the size of the cover and other considerations.

The means for positioning the face-plate relative to the cover consists of an integral flange 20, projected outwardly from the lower edge portion, preferably of the face-plate, which flange rests upon the foundation of the cover, being received Within said foundation.

It will thus be noted that the flange being received in the foundation, as above described, virtually holds the face-plate 7, positioned by the street paving or foundation, above the same. In other words and specifically speaking, the flange 20, as illustrated, may be received between a layer of bricks of the front wall 6 of the basin 9 and a second layer of bricks or like parts which composes the foundation of the street-gutter adjacent the inlet of the cover. The flange thus rigidly positions the face-plate 7 so that the same cannot move vertically and all likelihood of horizontal play or movement is prevented also.

The body 1, as has been before mentioned, rests upon a base-plate 3, and this plate is secured to the body by means of suitable fastenings and rests upon the foundation adjacent the outlet 8, leading into the basin. The front of the base-plate is cut away, as shown at 21, so that the face-plate 7 0f the cover is about flush with the front projected edge portions of this base-plate. The whole structure then combines a substantial and rigid arrangement of partswithout projecting portions.

The face-plate 7 is adapted for various adjustments as far as this position relative to the cover is concerned, and this adjustment is secured preparatory to paving the streets, the street-level determining the position of this part. After the necessary adjustment of the face-plate is secured the street foundation may be so laid as to rigidly position the flange 20, whereby the body of the face-plate is rigidly held in place at the desired elevation. The entire structure of the cover embodies a maximum degree of simplicity and rigidity.

In shipping the covers and for the purpose of protecting the face-plate 7 the latter has secured to the rear side thereof a filler-block 22. The face-plate is moved upwardly, so that the guide members 13 contact with the top plate 2, and the filler-block 22 is thus interposed between the upper flange 12 and the front portion of the base-plate 3. The faceplate 7 may be provided with an opening 23, through which a bolt or like fastening may be passed to secure the lillcr-block 22 in position. IV hen the cover has reached its destination and preparatory to setting it up for operation, the filler-block 22 is removed.

Having thus described the invention, what is claimed as new is 1. The combination of a catch-basin cover provided with an inlet-opening, a face-plate adapted for adjustable movement upon the cover and partially closing the opening thereof, a guide-flange projected rearwardly from said face-plate,guide-standards extended from said guide-flange, asupporting-bar connecting the guide-stand ards, and adjustable grate-bars supported by the said supporting-bar and adjustable longitudinally thereof.

2. The combination of a catch-basin cover provided with an inlet-opening, a face-plate adapted for adjustable movement upon the cover and partially closing the opening thereof, a guide-flange projected rearwardly from said face-plate,guide-standards extended from said guide-flange, asupporting-bar connecting the said guide-standards, and grate-bars comprising sections adjustably and removably mounted upon the supporting-bar.

In testimony whereof I aflix my signature in presence of two witnesses.
